Stephanie Kwolek was born in New Kensington, Pennsylvania in 1923. She received her bachelor's degree in chemistry from the Carnegie Institute of Technology in 1946. She went to work with DuPont where she worked in the textiles development division. She created a liquid polymer that when spun into fibers was extremely strong and durable.
